drivers: bus: simple-pm-bus: Fix compatibility with simple-bus for auxdata
After converting am335x to probe devices with simple-pm-bus I noticed that we are not passing auxdata for of_platform_populate() like we do with simple-bus. While device tree using SoCs should no longer need platform data, there are still quite a few drivers that still need it as can be seen with git grep OF_DEV_AUXDATA. We want to have simple-pm-bus be usable as a replacement for simple-bus also for cases where OF_DEV_AUXDATA is still needed. Let's fix the issue by passing auxdata as platform data to simple-pm-bus. That way the SoCs needing this can pass the auxdata with OF_DEV_AUXDATA. And let's pass the auxdata for omaps to fix the issue for am335x. As an alternative solution, adding simple-pm-bus handling directly to drivers/of/platform.c was considered, but we would still need simple-pm-bus device driver. So passing auxdata as platform data seems like the simplest solution.
